plant looks weak

Can someone tell me why a plant leans, even when you have nutes and good soil?

Gravity and available light. Is she supported?

im def a newbie i just threw a couple seeds in a bucket and let them alone..that was on april 6th 14 and im up in boston since then iv read alot of material but i just let them grow by themselves maybe watering them but now thew are 2 ft tall and just starting to flower cuz i brought them in under a flourescent tube but then the new top growth tuning lime green/yellow and twirling around and some other brown discoloration on th lower leaves...i was curious since i left the plats outside the whole time and then brought them in if that could caurse my problem?..iv flushed and put it in a bigger pot wit more soil and brought it back outside im hopeing that will help..any suggestions would be greatly appeciated..and srry if im doin this wrong but this is the first time iv come on to talk to ppl and dont kno the "protocol"..thanx

Put alittle air on your babies and they will stiffen up and get a bigger stalk

Yes she is, Idk if its my nutes.or what.
